News Flash! EVERYTHING MATTERS!!! Even 6” of wire. I have shotgun bi-wire spade cables and I STILL use banana jumpers, and it’s one of the best tweaks I’ve found and won’t listen without the jumpers. It’s crazy at a certain level how EVERYTHING matters in this stupid hobby of ours, but it just does. BTW, hook your cables to the lower binding posts as that’s where the power need is greatest.
To answer your question more directly, yeah it’s probably best to use the same cable for jumpers if you really like your speaker cables. That said, if you have big $$$ cables and it’s really expensive to make jumpers from them, I personally think if you pick cheaper but still good-quality jumpers that exhibit similar characteristics as your cables you’ll probably still be pretty happy and certainly better off than using the crap straps usually included with speakers. My cables are Acoustic Zen and jumpers are Stereovox (now Black Cat), and Chris Sommovigo was actually the guy who introduced me to the concept of using jumpers with shotgun cables and SO glad he did. Ignore jumpers, or anything really, at your peril. Hope this helps, and best of luck.
